Description

A kind of preparation method of automobile acoustical absorption carpet
Technical field
The present invention relates to a kind of preparation method of carpet more particularly to a kind of preparation methods of automobile acoustical absorption carpet.
Background technique
The absorptive product that the existing automobile primary carpet that has uses is generally divided into two kinds: blanket type and PU expansion type；Now with Country passenger car in-car air quality is required it is higher and higher, but the numerical value of the product VOC of PU foaming all occupy always it is high not Under, seriously affect the life security of motroist；Simple blanket type sound-absorbing effect is bad.
Therefore, to solve the above problems, providing a kind of new technical solution.
Summary of the invention
The present invention provides a kind of product made of thin red Buddhist nun's structural fibers fleece fabric and the bottom PET felt are laminating, makes it The preparation method of automobile acoustical absorption carpet with excellent sound absorption qualities and practicability.
The technical solution adopted by the present invention is that:
A kind of preparation method of automobile acoustical absorption carpet, the carpet are respectively from top to bottom A layers, C layers, B layers and D layers by four layers It is suppressed by high temperature, wherein A layers are fleece fabric layer, and B layers are horizontal lapping bottom carpet veneer, and C layers are PE film, and D layers are PEPA Anisotropic membrane,
Preparation method includes the following steps:
A, will thin red Buddhist nun's PET fiber, through shredding, mixing, combing, fold that lapping, the molding of needle thorn, raising is formed for being formed has The A layer of excellent sound absorption qualities；
B, by 3-D crimped fiber and L-PET fiber, through shredding, mixing, combing, lapping, needle thorn molding are folded, forms tool There are certain thickness and the B of elasticity layer；
C, the face PE of D layers of PEPA anisotropic membrane and B layers of bonding are got up with three roller blanchers, then through cooling, are finally made The bottom PET felt；
D, the one side of PEPA anisotropic membrane is not had to bond on the bottom the PET felt formed in A shell fabric and step c with PE film Come, forms automobile acoustical absorption carpet.
Preferably, the surface density of the fleece fabric layer is 500g/m2。
Preferably, the surface density of the bottom carpet veneer is 600 g/m2。
Preferably, the surface density of the PE film is 100g/m2。
Preferably, the surface density of the PEPA anisotropic membrane is 80g/m2。
Preferably, the 3-D crimped fiber mass percent is 60-70%, and the L-PET fiber quality percentage is 30-40%。
The beneficial effects of the present invention are:
A layers of product of the invention use thin red Buddhist nun's fiber, and pass through needle-punching with napping moulding process, unnumbered fibre Dimension is intersected blends together into countless fine gaps in a jumble, and sound can't get out once entering, and the channel inside fabric is too bad, sound Sound left right side that rushes in communication process is hit, and is gradually used up energy in the process, is achieved the purpose that sound-absorbing, makes the sound-absorbing effect of product It can achieve requirement；A layers are fleece fabrics simultaneously, have excellent fuzzy hand, substantially increase comfort and the sight of product Reward property；
B layer in the felt of the bottom PET has used 3-D crimped fiber, and passes through blanching treatment, forms fine and close fibrous layer, into One step absorbs acoustic wave segment；Meanwhile PEPA anisotropic membrane hinders bottom of car noise again and upwardly propagates, and reduces car Noise；
The PE film bond effect squeezed out with screw machine press is very good, so that product has excellent stripping performance, keeps away Exempt from product in use and generates lamination；Meanwhile PE film has certain sound insulation value, further reduced car and makes an uproar Sound；
By comparing with existing product, under identical frequency of sound wave, the sound-absorption coefficient of this product is significantly larger than existing The sound-absorption coefficient of product, therefore this product has excellent sound absorption qualities.
Specific embodiment
In order to deepen the understanding of the present invention, the present invention will be described in further detail with reference to the examples below, the embodiment For explaining only the invention, it does not restrict the protection scope of the present invention.
A kind of preparation method of automobile acoustical absorption carpet, the carpet are respectively from top to bottom A layers, C layers, B layers and D layers by four layers It is suppressed by high temperature, wherein A layers are fleece fabric layer, surface density 500g/m2, B layers are horizontal lapping bottom carpet veneer, and face is close Degree is 600 g/m2, C layers are PE film, surface density 100g/m2, D layers are PEPA anisotropic membrane, surface density 80g/m2,
Preparation method includes the following steps:
A, it by 100% thin red Buddhist nun's PET fiber, is formed and to be formed through shredding, mixing, combing, folding lapping, the molding of needle thorn, raising A layer with excellent sound absorption qualities；
B, by 60-70% 3-D crimped fiber and 30-40%L-PET fiber, through shredding, mixing, combing, lapping, needle are folded Thorn molding, forms the B layer with certain thickness and elasticity；
C, the face PE of D layers of PEPA anisotropic membrane and B layers of bonding are got up with three roller blanchers, then through cooling, are finally made The bottom PET felt；
D, the one side of PEPA anisotropic membrane is not had to bond on the bottom the PET felt formed in A shell fabric and step c with PE film Come, forms automobile acoustical absorption carpet.
The beneficial effects of the present invention are:
A layers of product of the invention use thin red Buddhist nun's fiber, and pass through needle-punching with napping moulding process, unnumbered fibre Dimension is intersected blends together into countless fine gaps in a jumble, and sound can't get out once entering, and the channel inside fabric is too bad, sound Sound left right side that rushes in communication process is hit, and is gradually used up energy in the process, is achieved the purpose that sound-absorbing, makes the sound-absorbing effect of product It can achieve requirement；A layers are fleece fabrics simultaneously, have excellent fuzzy hand, substantially increase comfort and the sight of product Reward property；
B layer in the felt of the bottom PET has used 3-D crimped fiber, and passes through blanching treatment, forms fine and close fibrous layer, into One step absorbs acoustic wave segment；Meanwhile PEPA anisotropic membrane hinders bottom of car noise again and upwardly propagates, and reduces car Noise；
The PE film bond effect squeezed out with screw machine press is very good, so that product has excellent stripping performance, keeps away Exempt from product in use and generates lamination；Meanwhile PE film has certain sound insulation value, further reduced car and makes an uproar Sound；
By comparing with existing product, under identical frequency of sound wave, the sound-absorption coefficient of this product is significantly larger than existing The sound-absorption coefficient of product, therefore this product has excellent sound absorption qualities.
Existing product and this product sound-absorption coefficient contrast table are as follows
